To support this mission, we are seeking a Senior Cybersecurity Engineer to protect and defend critical enterprise and mission IT infrastructures. In this role, you will be at the forefront of securing complex, multi-classification architectures, ensuring that the data and technology powering our nation's most sensitive missions remain resilient against evolving threats. You will have a direct impact on the security posture of cloud environments and classified enclaves, bridging the gap between high-level policy and technical implementation.
Key Responsibilities- Secure enterprise and mission IT infrastructures across diverse operating systems, networks, and web/database applications.
- Manage and harden storage, boundary/perimeter devices, and logging/monitoring solutions within cloud environments (e.g., C2S) and classified enclaves.
- Implement policy-based protections for data flows and network boundaries across complex, multi-classification architectures.
- Support security certification and accreditation activities (RMF) and lead the development of required security documentation.
- Perform ad-hoc penetration testing, formal red/blue team exercises, and compliance assessments of classified Federal systems.
- Identify innovative protection strategies that align with budget and infrastructure constraints.
- Communicate and brief technical risks and mitigation options to both technical and non-technical stakeholders.
- Prioritize and coordinate cybersecurity workflows in fast-paced, high-stakes environments.
Required Experience/Clearance- Active TS/SCI security clearance.
- 10+ years of experience in cybersecurity engineering or information assurance.

- Demonstrated expertise in network boundary protection and policy-based data flow implementation.
- Experience with the Risk Management Framework (RMF) and the security accreditation process.
- Hands-on experience with penetration testing tools and red/blue team methodologies.
- Must possess and maintain relevant cybersecurity professional certification(s) (e.g., CISSP, CEH, Security+, or equivalent DoD 8140/8570.01-M certification).
Desired Experience- Familiarity with DataBricks, GitLab, or Jira for managing security workflows.
- Experience with advanced logging and monitoring solutions like Splunk or ELK stack.
- Knowledge of Spark or other big data technologies within a secure environment.
- Advanced degree in Cybersecurity, Computer Science, or a related technical field.
- Previous experience supporting Intelligence Community (IC) or Department of Defense (DoD) customers.
